Final answer:
To find the area of a square block with sides measuring 3x+8 meters, you square the expression, resulting in the area being (3x+8)² square meters.
Step-by-step explanation:
The student asked about finding the area of a square city block where the measure of each side is given by the expression 3x+8 meters. To find the area of a square, we use the formula Area = side × side. Since each side of the city block is 3x+8 meters, the area will be (3x+8) squared, which means we multiply (3x+8) by itself.
To solve for a specific value of x, the value would be substituted into the expression, and then we would perform the operations to square the expression. However, since no specific value for x is given, the answer to the question will remain in terms of x, which means the area in terms of x is (3x+8)² square meters.
